ELECTRICAL CONDUCTOR.

SPECIFICATION forming part of Letters Patent No. 303,735,

dated August 19, 1 884.

Application filed December 8. 1882. (No model.)

Figure 1 is a side view and partial sectionalview representing my said invention. Fig. 2is a longitudinal sectional view of the same, taken in the line a: x of Fig. 1; and Fig. 3 is a transverse sectional view of the same.

A andB are two strips of paper,which may be of any desired thickness, width,or length,

but which in practice will ordinarily be, say, one inch wide, of the thickness, more or less, of Manila paper, so called, and of a length proportioned to the distance through which the electrical current is to be passed.

0 C are flat thin strips of sheet-copper, which in practice may be about one-quarter of an inch, more or less, in width, and which are placed between two thicknesses, A B, of paper, the said strips being at a distance of, say, one-fourth of an inch, more or less, from each other. The strips A B of paper are cemented together by means of glue, paste, or other suitable cementing or adhering material, and the paper being to all practical intents and purposes a non-conductor, the two strips or conductors O are insulated, not only fronreach other, but from contact, connection, or communication with conductors external to the paper A B, except where the same may be designedly connected at their ends.

In order to apply the conductors in placeas, for example, for transmitting the current of an electriclight, so called the device is placed flatwise upon the walls or ceiling of the building and attached thereto.

In order to provide for the cheap, efficient, and convenient attachment of the device to the wall or ceiling, as aforesaid, the outer surface of one of the strips of paper is coated -most cases comprise with gum or mucilage, so called-such, for example,as is used upon the adhesive fiaps of letter-envelopes-so' that by moistening this coating of gum and then pressing the gummed surface of the device against the surface of the wall or ceiling, as the case may be, the device is firmly held in place. When prefcrred,this last-mentioned featnrethe use of the adhesive material for attaching the device in positionmay be dispensed with, and the device attached in-any other suitable way. It is much preferred, however, that this feature of the invention be embraced in the construction of the device, inasmuch as it provides a cheap,simple,and cfiicient means of jafiixing the device in piace.

By means of my invention I avoid disfiguring the walls or ceilings of rooms, as is incident to the use of .the conductors of electricity hitherto used for electric lights'and similar purposes. -Furthermore, by means of my said invention I secure a great economy of time and labor in putting up and taking down the electrical conductors, and I also avoid the necessity of driving tacks or nails in walls, and of tearing up floors, 85c. When desired, the outer surface of the outermost strip, A, of paper, may be made of a color to correspond to that of the painting or. pa per of the wall or ceiling, or it may be painted over with the same color or tint of such wall or ceiling, and thus be made practically unobservable.

3 It is of course to be understood that while for all practical purposes-as, for example, in electric lighting, &0.i3il6 device should, in two parallel strips of the fiat sheet-copper confined in relation with each other, as hereinbefore explained, yet where it is desired that only a single strip shall be employed, such may be done as within the scope of my invention. Furthermore, although copper is, of course, the best conducting material, yet, when desired, the strips C 0 may be made of iron or other suitable metal.

What I claim as my invention, is;-

1. The combination of one or more metal lic strips, 0, with two conjoined strips, A B, of paper cemented together and inclosing the metallic strips or conductors between them to IOO insulate the same, substantially as and for the inclosing the metallic conductors between purpose herein set forth.

2. The combination of an external coating herein set forth.

of gum or adhesive material with the device CHARLES. TEMPLE JACKSON. 5 composed of one or more flat metaliic con- Witnesses: ductors of electricity inclosed between two THOMAS E. CROSSMAN,
